ANTONIO PELLETIER, OF WASHINGTON, DISTRICT OF COLUMBIA.

METHOD OF LAYING PAVEMENTS.

SPECIFICATION forming part of Letters Patent No. 230,492, dated July 27, 1880,

Application filed December 4, 1879.

which form a part of this specification.

This invention relates to an improved method of laying pavements; and it has for its object to provide a firm and substantial concrete base or foundation for the paving-blocks, so constructed that portions of the said base may be readily removed for repairs or to get access to water or gas pipes without injury to adjacent portions, and the invention further relates to a paving-block formed of concrete or bton of any suitable description, and are constructed by molding, with beveled edges at the top, and said top being slightly rounded, as more fully hereinafter specified.

My invention consists in laying upon a roadbed a series of strips of wood, or other sufficiently rigid material, crossing each other at angles, so as to form diamond or rectangular s1: aped spaces, in which the concrete or bton is laid, a cushion-layer composed of silicious sand or gravel mixed with bitumen, and a paving-block formed of concrete, constructed by molding, havingits entire top edges beveled, so as to form a slightly rounded surface.

In the drawings, Figure 1 represents a plan view of my improved pavement with a portion of the surface blocks removed, showing the foundation; Fig. 2, a longitudinal sectional, and Fig. 3 a perspective, view of one of the paving-blocks.

The letterA indicates the natural road-bed, properly rolled for the reception of the pavemerit, and B a series of strips of wood laid thereon and crossing each othgr at angles, in the present instance at oblique anglesso as to form a series of diamond-shaped spaces, 0, in which the bton or concrete is laid and tamped in the usual manner.

After the foundation has been properly laid, a cushion-layer, D, composed of silicious sand or gravel mixed with bitumen, may be applied, after which the paving-blocks are laid.

These blocks are formed of concrete or bton of any suitable description, and are constructed by molding, with beveled edges at the top, which, when laid, form recesses which may be filled with sand, and the said top, being slightly rounded, gives the desired foothold to draft-animals.

In paving streets where railroads are employed, I lay the blocks adjoining the sides of the track lengthwise, which gives afirmer hearing to the wheels of the cars.

The beton for the foundation and for the paving-blocks may be of any description, as above stated; but my invention is especially designed to be used in connection with the bton or concrete compounds, consistingof broken stone or gravel, hydraulic lime of tiel, terra-alba, hydraulic lime or cement, or any similar cement, and silicious sand, oxide of iron, and a chloride either of iron, manganese, or calcium, as described in the Letters Patent of the United States granted to me the 29th day of October, 1879, and numbered 221,096, for improvements in concrete pavements.

I am aware that foundations have heretofore been laid by placing a series of strips upon the road-bed, forming frames, in which the concrete is laid, and this I do not claim, broadly; but

What I claim as new, and desire to secure by Letters Patent, is

1. A paving-block formed of concrete, having its entire top edges beveled so as to form a slightly rounded surface, and adapted, when ANTONIO PELLETIER.
